To solve the Cube, you need special skills and understanding. For example, pattern recognition is very important to solve the Cube.

If you are not able to do something, that is true for the present, not for the future. All the time there's a chance to go a step further. Not to be frustrated.

My main profession is architect.

The Cube was a wonder - a wonder for itself and a wonder for myself. To me, it was much more strange than to anybody else.

I'm kind of surprised that so many of those other books were almost exactly like mine. They even follow the form. There were some books that even copied the stamp. It shows so little imagination.

I think great art comes from being open and creative with somebody, and of course, if feelings start getting involved in that, it can either make things fantastic or really messy.

Doing something that is your passion, in my case related to music and art, being a performer playing shows around the world, that is a dream come true.

Essentially, I'm untrained, so I just go with my imagination and try to put myself as solidly as I can into the shoes of whatever person I'm going to be playing.
